Abstract
In this study, an elastic-plastic stress analysis was carried out in woven steel fibers- thermoplastic clamped composite laminates. The stacking sequences were chosen as [0/0]2, [15/-15]2, [30/-30]2 and [45/-45]2 for woven steel fibers – thermoplastic composites plates. The layers were chosen for symmetric and antisymmetric cases. The finite element solution was performed by using the ANSYS software. Solid 186 element was utilized in the solution. Normal stress components at the clamped edges were found to be higher than that at the mid point of the laminated plates. Normal stresses are tensile at the mid point of the clamped edges and compressive at the mid point of the laminated plates. Then, the residual stress components were calculated in the critical points of the composite laminates.
Highlights
Thermoplastic composites gain some advantages in nowadays
Damb and Hansen [11] developed a numerical model for prediction of the process-induced thermal residual stresses in the thermoplastic composite laminates
Parlevliet et al [12] reviewed thermal residual stresses in thermoplastic composites arising at high temperatures
Summary
Thermoplastic composites gain some advantages in nowadays. Since its high impact resistance and reform again very the use of the thermoplastic composites increases in the industry. Sayman [4] carried out an elasto-plastic stress analysis in aluminum metal matrix laminated plates loaded transversely by using finite element technique. Some investigations were performed in metal-matrix composite laminates using finite element methods [6,7,8,9]. Shih and Loos [10] investigated heat transfer analysis of the thermoplastic filament winding process They determined the temperature distribution in the composite during the fabrication process by using the ABAQUS transient heat transfer finite element model. Özcan [13] performed elastic-plastic stress analysis in steel fiber reinforced thermoplastic composite laminated plates under in-plane loading. An elastic-plastic stress analysis was carried out in a steel fiber reinforced thermoplastic clamped plate using a finite element technique
